Many ecological studies produce species lists. In enchytraeids, these records are often the
primary source of information for the distribution of species, and for their ecological behaviour
as well. However, only very rarely are these records documented by voucher specimens. This
negligence may be explained by the fact that enchytraeids are usually determined in vivo, but it
leads to the situation that an independant control of the results is not possible. Moreover,
taxonomic revisions can change the meaning of names, for example when a given species
turns out to exist of more than one species. A comprehensive taxonomic revision of one
enchytraeid genus (Fridericia) (Schmelz 2003, Abh. Naturwiss. Ver. Hamburg NF 38) detected
a high percentage of misidentifications in the few available reference collections and unmasked
up to six different and morphologically distinguishable species under the same species name
used by different authors. Besides, several of the most-cited nominal species had to be redefined.
As a consequence, species records without available voucher material had to be considered
as unreliable and could not be used as source of information. In this paper we give an account of
the loss of information caused by the lack of reference material, which amounts to over 80% of
the records in some species. On the other hand, in the same revision the accuracy of an
identification could be verified or rejected whenever preserved specimens were available. Most
of them had been fixed simply with ethanol or formol.
This leads to a list of requirements for ?Good Taxonomic Practice? in studies with enchytraeids,
with two basic principles: (1) Any published record of enchytraeid species should be documented
with voucher specimens. (2) They should be deposited in Natural History Collections with
curatorial service. GTP should be standard even when supposedly unproblematic or trivial species
are recorded. Although we only deal with enchytraeids here, GTP may also apply to other taxa of
the soil mesofauna.
